Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Merchant Alliances The Company maintains various ownership interests in merchant alliances and strategic investments in companies in related markets. At September 30, 2020, the Company had 16 affiliates, the most significant of which are related to the Company’s merchant bank alliance affiliates. A merchant alliance, as it pertains to investments accounted for under the equity method, is an agreement between the Company and a financial institution that combines the processing capabilities and management expertise of the Company with the visibility and distribution channel of the bank. A merchant alliance acquires credit and debit card transactions from merchants. A significant portion of the Company’s business is conducted through merchant alliances between the Company and financial institutions. To the extent the Company maintains a controlling financial interest in an alliance, the alliance’s financial statements are consolidated with those of the Company and the related processing fees are treated as an intercompany transaction and eliminated in consolidation. To the extent the Company has significant influence but not control in an alliance, the Company uses the equity method of accounting to account for its investment in the alliance. As a result, the Company’s consolidated revenues include processing fees, administrative service fees, and other fees charged to merchant alliances accounted for under the equity method. Such fees totaled $47 million and $134 million for the three and nine months ended September 30, 2020, respectively, and $31 million for both the three and nine months ended September 30, 2019. No directors or officers of the Company have ownership interests in any of the alliances. The formation of each of these alliances generally involves the Company and the bank contributing contractual merchant relationships to the alliance and a cash payment from one owner to the other to achieve the desired ownership percentage for each. The Company and the bank enter into a long-term processing service agreement as part of the negotiation process. This agreement governs the Company’s provision of transaction processing services to the alliance. The Company had $36 million and $35 million of amounts due from unconsolidated merchant alliances included within trade accounts receivable, net in the Company’s consolidated balance sheets at September 30, 2020 and December 31, 2019, respectively. Effective July 1, 2020, the Company and Bank of America dissolved their BAMS joint venture, of which the Company maintained a 51% controlling ownership interest. Upon the dissolution of the operations, the joint venture transferred a proportionate share of value, primarily the client contracts, to each party via an agreed upon contractual separation. The revenues and expenses of the BAMS joint venture were consolidated into the Company’s financial results through the date of dissolution. See Note 4 for additional information. Joint Venture Transition Services Agreements Pursuant to certain transition services agreements, the Company provides, at fair value, various administration, business process outsourcing, and technical and data center related services for defined periods to the Lending Joint Ventures and Investment Services business (see Notes 4 and 8). Amounts transacted through these agreements totaled $16 million and $9 million during the three months ended September 30, 2020 and 2019, respectively, and $43 million and $27 million for the nine months ended September 30, 2020 and 2019, respectively, and were primarily recognized as processing and services revenue in the Company’s consolidated statements of income.
